A Broncos model freight train is seen on display at the Colorado Model Railroad Museum of the Greeley Freight Station Museum. The model first appeared at the museum, which houses the longest single track in the country, Jan. 17 and will remain on display through the Super Bowl on Feb. 2. Staff at the museum modified the Broncos train to run the track after receiving the model from the Danbury as a way to show the Broncos support and wish them luck, according to Executive Director Michelle Kempema.
